The fact that you have lived seventy or eighty years means that you have some advantages that should help you in helping others. It means you have experiences and hopefully you have acquired some wisdom as well.
Your family and friends may love you and respect you, but they do not want you to push your influence on them. You must be smart in how you go about things.,
Being critical will probably not help. Whining certainly won’t be received well.
Showing your love, keeping a good spirit, smiling and reflecting the joy of the Lord will give you a much stronger platform for communicating your influence.
The generations coming after you need you so gear up for it and see if you can help them get where they need to be.
